记HIVE一个问题

Others 2021-11-20 06:36:40 views: null

原来是用来sqoop将mysql数据导入hdfs lzo压缩保存，再将数据解压缩保存至ods层
ods层创外部分区表语句存储如下：

STORED AS
        INPUTFORMAT 'com.hadoop.mapred.DeprecatedLzoTextInputFormat'
        OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'

指定存储方式，读数据采用LzoTextInputFormat；输出数据采用TextOutputFormat
后来由于需要补数据发现，无法从其他表往此表导入此格式数据
